OAR-LOCK.

Application filed August 27. 1910.

To all whom it may concern;

Be it known that I, l nnnnnicn l).S'l.-\l2tl\', a citizen of the linited States, and a resident of Whitewater, in the county of Walworth and State of \Visconsin, have invented a new and Improved ()air-lmelnol? which the following is a full, clear, and exact specititaition.

This invention relates to oar locks, and more particularly to such as are constructed in a manner permitting o'l their adjustment to counteract the e'tlects produced through wear.

The object oi the invention is to provide a device of the class described, of simple and serviceable construction, inex 'iensive to manufacture, which is adjustable so as to render the oar locks practitailly noiseless while in operation, and also to overcome los motion occasioned through wear.

The invention consists in the construction and combination of parts to be more particularly described hereimrt'ter, and partie nlarly set forth in the claim.

Reference is to be had to the accompanying drzuvings 'torming a part of this specification, in which similar cha 'acters oli reterence indicate corresponding parts in all the figures.

Figure l is a side elevation of my invention: l ig. 2 is a. cross sectional view or: the line 2--2 of Fig. 1; Fig. 3 is a side elevation of the stem, having a portion broken away; and Fig. -t represents a wedge with which the bifurcated ends ol the stem may be adjusted.

Before proceeding with a more detailed description o'li' my invention it should be understood that great dilliculty is experienced in the use of oar locks when the latter become worn by too long use. \Vhen the ordinary oar lock has been in operation for some time, the stem and socket. respectively, become worn, causing the tormcr to move too freely in the latter, and thereby hindering rowing, and producing a disagreeable metallic sound. To obviate these dittieulties l have constructed an oar look as above described, which combines an ad- Specification of Letters Patent.

jnstable stem and socket, and by the adjustment ol either or both o'l these parts l may at all times preventthe stem 'lrom moving too freely in its socket.

Referring more specilically to the drawings, I provide a bow 1 ol the conventional lorm and adapted to receive an oar and having a stem 2 integral therewith. The stem has its lower extremity bil urcated and separated an appreciable distance. as shown most clearly in Fig. Ci ol the drawings. Located on the stem is a seating llange 23, which rests upon the upper edge of a socket -l. The socket has its upper portion bit'ureated and spaced to allow of adjustment, as shown in l ig. 1 of the drawings. I have employed a base 5 upon which the socket 4: is mounted. braces t3 being used to hold the socket rigidly in place.

ii'l ter my oar lock has been in use and the stem and socket have become worn so that the elliciency ol the device is impaired, l prel'erably employ a wedgeshaped member such as is shown in the drawings, to spread the bifurcated end of the stem. ll", however, this does not obviate all the lost motion, l can by means o'l any suitable instrument, such as a pair of pliers, or the like, contact the bilurcated end of the socket so that it will snugly receive the stem.

llaving thus described my invention. I claim as new, and desire to secure by Letters Patent,-

ln an oar lock. provided with a stem, the end of which is bilurcated, a socketadapted to receive said stem, opposite sides o'l. said socket being split in line with the bi ilureating cut in said stem, and a wedge inserted in said biturcating out. whereby said stem and socket are 'l rictionally locked together.

In testimony whcreoli I have signed my name to this specilication in the presence ol two subscribing witnesses.
